Chapter 12 Configuring IP Logging

Configuring Manual IP Logging for a Specific IP Address

•minutes—Specifies the duration the logging should be active. The valid range is 1 to 60 minutes. The default is 10 minutes.

•numPackets—Specifies the maximum number of packets to log. The valid range is 0 to 4294967295. The default is 1000 packets.

•numBytes—Specifies the maximum number of bytes to log. The valid range is 0 to 4294967295. A value of 0 indicates unlimited bytes.

Note The minutes, numPackets, and numBytes parameters are optional, you do not have to specify all three. However, if you include more than one parameter, the sensor continues logging only until the first threshold is reached. For example, if you set the duration to 5 minutes and the number of packets to 1000, the sensor stops logging after the 1000th packet is captured, even if only 2 minutes have passed.

Configuring Manual IP Logging

To manually log packets on a virtual sensor for a specific IP address, follow these steps:

Step 1 Log in to the CLI using an account with administrator or operator privileges.

Step 2 Start IP logging for a specific IP address.

sensor# iplog vs0 192.0.2.1 duration 5

Logging started for virtual sensor vs0, IP address 192.0.2.1, Log ID 1 Warning: IP Logging will affect system performance.

sensor#

The example shows the sensor logging all IP packets for 5 minutes to and from the IP address 192.0.2.1.

Note Make note of the Log ID for future reference.

Step 3

Monitor the IP log status with the iplog-statuscommand.

Note Each alert references IP logs that are created because of that alert. If multiple alerts create IP logs for the same IP address, only one IP log is created for all the alerts. Each alert references the same IP log. However, the output of the IP log status only shows the event ID of the first alert triggering the IP log.

For More Information

•To stop logging IP packets for a specific IP address, see Stopping Active IP Logs, page 12-6.

•To log IP packets as an event associated with a signature, see Configuring Automatic IP Logging, page 12-2.

IPS4510K9 specifications

Cisco Systems has long been a leading player in network security, and its IPS (Intrusion Prevention System) series is a testament to its commitment to safeguarding digital environments. Among its notable offerings are the IPS4510K9 and IPS4520K9 models, both designed to provide advanced threat protection for mid-sized to large enterprise networks.

The Cisco IPS4510K9 and IPS4520K9 are distinguished by their cutting-edge features that help organizations defend against a myriad of cyber threats. These systems utilize a multi-layered approach to security, integrating intrusion prevention, advanced malware protection, and comprehensive visibility across the network.

One of the primary characteristics of the IPS4510K9 is its high performance. It boasts a throughput of up to 1 Gbps, making it suitable for environments that demand rapid data processing and real-time responses to threats. The IPS4520K9, on the other hand, enhances that capability with improved throughput of up to 2 Gbps, accommodating larger enterprises with heavier network traffic. These models are equipped with powerful processors that support complex signature matching and can intelligently distinguish between legitimate traffic and potential threats.

In addition to performance, both models are designed with scalability in mind. They can be easily integrated into existing Cisco infrastructures. This facilitates a seamless enhancement of security without causing significant interruptions to ongoing operations. Moreover, they offer flexible deployment options, allowing organizations to operate them inline or out of band depending on their specific needs.

The Cisco IPS4510K9 and IPS4520K9 leverage advanced detection technologies, utilizing a variety of signature types and heuristic analysis to detect known and unknown threats effectively. They are equipped with real-time alerting and reporting capabilities, giving security teams immediate visibility into potential breaches and enabling them to respond swiftly.

Furthermore, both models support a range of management options through the Cisco Security Manager, allowing for centralized administration, streamlined policy management, and enhanced monitoring capabilities. Automated updates ensure the systems remain current with the latest threat intelligence, vital for staying ahead of evolving cyber threats.

In summary, the Cisco Systems IPS4510K9 and IPS4520K9 represent powerful solutions for organizations seeking robust intrusion prevention capabilities. With their high performance, scalability, and advanced detection technologies, these systems are essential tools in the ever-changing landscape of cybersecurity, providing enterprises with the peace of mind needed to operate securely in today's digital world.
